Product Overview:
Room temperature monitoring and fan coil control regulate indoor HVAC conditions according to the selected settings and detected environmental conditions. The Schneider Electric (Viconics) VT7350C5531E is an OEM low-voltage fan coil room controller designed for commercial HVAC applications. It provides two floating or on/off outputs and supports Echelon network communication for connected building control systems.
Floating and On/Off Output Control:
The controller provides two independent outputs that can be configured for on/off or floating operation. These outputs support control of compatible fan coil equipment and associated HVAC components. The selected output configuration determines how the connected equipment responds to the controller's temperature-control signals.
Floating and On/Off Output Control:
The VT7350C5531E includes a passive infrared (PIR) occupancy sensor cover and an integrated humidity sensor. The occupancy sensing function supports occupied, standby, and unoccupied control modes. Humidity monitoring provides additional environmental information for applications requiring humidity-based control.
Replacement Guidelines:
Replace the controller if its display or controls become unresponsive, communication with the building automation network is interrupted, or its outputs fail to operate correctly. Before ordering, verify the VT7350C5531E part number, two-output configuration, Echelon communication protocol, PIR sensor arrangement, and humidity-sensing requirements. Confirm that the existing fan coil system supports the required output and communication configuration.
Common Failure Symptoms:
- Fan coil equipment does not respond to thermostat commands
- One or both control outputs fail to operate
- Temperature regulation becomes inconsistent
- Communication with the Echelon network is interrupted
- Occupancy detection does not respond correctly
- Humidity readings are unavailable or inconsistent
- Display or adjustment controls become unresponsive
Equipment Compatibility:
The Schneider Electric (Viconics) VT7350C5531E is designed for low-voltage fan coil unit applications in commercial buildings. Its two floating or on/off outputs support compatible fan coil control arrangements, while Echelon communication allows integration with supported building automation networks. The VT7350 series also includes related configurations such as VT7350C5031, VT7350C5031B, VT7350C5531B, and VT7350C5531P. These models have different output or communication configurations and should not be treated as direct replacements without checking system requirements.
